1. Google both terms. The definition is the first thing up for both . . .

2. Gaslighting is from an old movie with Ingrid Bergman and Charles Boyer

The woman's husband was playing tricks on her to make her seem that she was the crazy one ... lowering the gas lamps to cause changes in the lighting of the house and denying that there was any change in the light ... all types of tricks like that. So, the in the political sense, Republicans denying that there is anything going on; all is normal; we are crazy; we are paranoid.

Ratfuck is from the Donald Segretti days of Watergate. When you play political tricks on your opponent ... ordering 1000 pizzas to your opponent's rally and then getting them stuck with the bill. Stuff like that.

4. Gaslighting

5. Ratfucking is a Nixonian term revived to describe Karl Rove's methods.

Conscienceless trickery, that's essentially what it is. Damaging a political system in a hundred different ways to defeat meaningful progress because one chooses the path of the cunning orc instead of the human citizen.

Russians have redefined it. They kind of own it now.

Passive aggressive is burning the toast because you don't want to argue.

7. Passive aggressive. See Melania.

10. Gaslighting is like asserting what someone experienced didn't happen

Gaslighting is a malicious and hidden form of mental and emotional abuse, designed to plant seeds of self-doubt and alter your perception of reality. Like all abuse, it's based on the need for power, control, or concealment. Some people occasionally lie or use denial to avoid taking responsibility. They may forget or remember conversations and events differently than you do, or they may have no recollection — say, due to a blackout if they were drinking. These situations are sometimes called gaslighting, but the term actually refers to a deliberate pattern of manipulation calculated to make the victim trust the perpetrator while doubting his or her own perceptions or sanity, similar to brainwashing. (See “How to Spot Manipulation.”)

The term derives from the play of the same title, and later, the film with Ingrid Bergman and Charles Boyer in which Bergman plays a sensitive, trusting wife struggling to preserve her identity in an abusive marriage to Boyer, who tries to convince her that she’s ill in order to keep her from learning the truth.

Gaslighting Behavior

As in the movie, the perpetrator often acts concerned and kind to dispel suspicions. Someone capable of persistent lying and manipulation is also quite capable of being charming and seductive. Often the relationship begins that way. When the gaslighting starts, you might even feel guilty for doubting a person you’ve come to trust. To further play with your mind, an abuser might offer evidence to show that you’re wrong or question your memory or senses. More justification and explanation, including expressions of love and flattery, are concocted to confuse you and reason away any discrepancies in the liar’s story. You get temporary reassurance, but you increasingly doubt your own senses, ignore your gut, and become more confused.

The person gaslighting you might act hurt and indignant or play the victim when challenged or questioned. Covert manipulation can easily turn into overt abuse, with accusations that you’re distrustful, ungrateful, unkind, overly sensitive, dishonest, stupid, insecure, crazy, or abusive. Abuse might escalate to anger and intimidation with punishment, threats, or bullying if you don’t accept the false version of reality.

Gaslighting is a form of psychological manipulation that seeks to sow seeds of doubt in a targeted individual or in members of a targeted group, making them question their own memory, perception, and sanity. Using persistent denial, misdirection, contradiction, and lying, it attempts to destabilize the victim and delegitimize the victim's belief.[1][2]

Instances may range from the denial by an abuser that previous abusive incidents ever occurred up to the staging of bizarre events by the abuser with the intention of disorienting the victim. The term owes its origin to the 1938 Patrick Hamilton play Gaslight and its 1940 and 1944 film adaptations. The term has been used in clinical and research literature,[3][4] as well as in political commentary.[5][6]

The term originates in the systematic psychological manipulation of a victim by her husband in the 1938 stage play Gaslight, known as Angel Street in the United States, and the film adaptations released in 1940 and 1944.[7] In the story, a husband attempts to convince his wife and others that she is insane by manipulating small elements of their environment and insisting that she is mistaken, remembering things incorrectly, or delusional when she points out these changes. The original title stems from the dimming of the gas lights in the house that happened when the husband was using the gas lights in the flat above while searching for the jewels belonging to a woman whom he had murdered. The wife correctly notices the dimming lights and discusses it with her husband, but he insists that she merely imagined a change in the level of illumination.[citation needed]

The term "gaslighting" has been used colloquially since the 1960s[8] to describe efforts to manipulate someone's perception of reality. In a 1980 book on child sexual abuse, Florence Rush summarized George Cukor's Gaslight (1944) based on the play and wrote, "even today the word [gaslighting] is used to describe an attempt to destroy another's perception of reality."[9]
